Lanthanum-Dominant Rare Earth Oxide Mixture from Mexico
A chemically defined mixture of rare-earth oxides where lanthanum oxide (La2O3) is the predominant component, typically containing 40-60% lanthanum oxide alongside smaller amounts of neodymium, praseodymium, and cerium oxides. This product falls under HTS 2846.90.20.05 as it is a mixture of rare-earth oxides (excluding cerium oxides as predominant) with lanthanum as the main metal. Used primarily in ceramics, glass polishing, and as a precursor for catalysts.

Import Tips
• Verify composition certificate from supplier confirming lanthanum >50% of rare-earth content to avoid reclassification to 2846.90.20.15 (cerium-dominant)
• Include assay reports and SDS for CBP review; ensure packaging prevents moisture absorption which could alter oxide purity
